Very good point re. Braille readers. I was being flippant and did not think of that. My apologies. Tabs for indentation may be useful there. as would a blind-friendly pre- and post- processor for programming language specific files (a braille liner, could call it black-er for python :)

I don't know how braille readers actuality work, but I guess they process a bytestream. How do they handle utf-16 and other non standard character sets? This is a known problem for a lot of systems- it would be interesting to know how they address it.
